Determining the number of Air Changes Per Hour or (ACH) is crucial when choosing an air purification system. Which model and how many units you will need for your air purification needs? The following data has been gathered from various sources. We continually look to ASHRAE , the EPA, and Engineering websites for newly updated clean air information. The lists below shows engineering recommendations for the number of air changes needed in specific buildings and rooms. Your needs may vary. We also include a table on required air changes per occupant. Using these charts you should be able to determine how much air purification you need.
Air changes can be done by bringing in fresh outdoor air or by indoor air purification. The combination of both air purification and makeup air is often a great answer. Remember these are only recommendations. If you need more help planning the Indoor Air Quality for your business or home, please give the experts at LakeAir a call @ 800-558-9436.
